Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
This build is made to get, what i think is, the most out of ezreal. I bring clarity because ezreal's mana is his life for this build. Ghost becasue he is one of the slowest characters in the game, his base speed is less than mordekaisers. I max out mystic shot first becasue, until zhonyas ring his other abilities are quite weak and his mystic shot uses low mana and lowers colldowns. His w is useful for team fights as it heals so max that second but always get at least one in arane shift as it can be used to line up shots, chase, get away from or to enemies. ALways level his ult when you can.
Get rod of ages early, it gives a little ap for you and raises both your health and mana. Boots of swiftness are very important as he is slow, and the rest of this build should be self explanitory as it is meant to power you up; rylais and the void staff are interchangable, i prefer rylais as it slows and gives health.
